Mike Pompeo is confirmed for the job of chief diplomat. He immediately left on a business trip to Europe. The role is challenging under a President who is openly hostile to most international cooperation, and it comes after a series of Secretaries of State who had strongly differing takes on what made them effective. Hillary Clinton, for instance, spent a huge amount of time on the road; Colin Powell wrote that he thought the Secretary of State ought to rely more on others to do the legwork. It's a storied role, to be sure: Jefferson, Madison, and Monroe all occupied it.
